chore(mediacrawler): checkpoint local login changes

[josh87523]

Summary

• checkpoint local login-related changes on the existing task branch
• add repository hygiene ignores and a short business/product logic note
• merge current upstream/main to clear PR merge conflicts

Discovery Gate

用户目标

• 完成 stop hook 判定未闭环的 MediaCrawler 工程收尾：清理 dirty tree、提交、push、确认 PR 和验证 gate。

任务分类

• C：既有分支收尾与冲突自愈，不新增架构/第三方集成；后续因 PR DIRTY 升级为 L2 merge-conflict closure。
• 调研结论：基于现有分支和 Workspace finisher/PR validation 改造，不从零实现。

AI 推断的相关面清单

• source/caller: media_platform/douyin/login.py, media_platform/douyin/client.py, media_platform/tieba/*, cmd_arg/arg.py
• tests/fixtures/contracts: tests/test_cmd_arg_tieba.py, tests/test_tieba_client_pagination.py, tests/test_tieba_extractor.py, test/test_utils.py
• docs/history: README.md, README_en.md, docs/business-product-logic.md, CDP guide/common questions docs
• config/env: pyproject.toml, uv.lock, .gitignore; no env/secrets edited
• runtime/release surface: no local launchd/release entrypoint for this repo in scope
• external side effect: GitHub PR/branch push only

证据

• finisher initially reported dirty tree and missing PR recognition
• gh pr view confirmed PR chore(mediacrawler): checkpoint local login changes #880 head d5fafb8 and earlier DIRTY merge state
• upstream/main merged into this branch; .gitignore and uv.lock conflicts resolved
• uv.lock parse issue self-healed by removing stale duplicate tuna package records inconsistent with current pyproject default index

不确定项 / 需要用户拍板

• none for local closure; merge is subject to upstream repository permissions/review/checks

验证矩阵

• local: git diff --check passed
• contract: uv lock --check passed; uv lock completed
• smoke: uv run pytest test/test_utils.py tests/test_cmd_arg_tieba.py tests/test_tieba_client_pagination.py tests/test_tieba_extractor.py => 18 passed
• online: not applicable; no live runtime/launchd/release entrypoint touched
• external endstate: branch pushed to origin/chore/dirty-worktree-checkpoint-20260422 and PR chore(mediacrawler): checkpoint local login changes #880 updated

Validation

• uv lock --check
• uv lock
• uv run pytest test/test_utils.py tests/test_cmd_arg_tieba.py tests/test_tieba_client_pagination.py tests/test_tieba_extractor.py
• python3 /Users/obayotian/Workspace/scripts/codex_pr_validation.py --cwd /Users/obayotian/Workspace/MediaCrawler --run --json
